◆ crc32()

std::uint32_t FEAT::Hash::crc32 ( std::size_t  n,
const void *  buffer 
)
static

Computes the CRC-32 checksum of a buffer.

The polynomial for the CRC table is 0x04C11DB7.

Parameters
[in]nThe length of the input buffer in bytes.
[in]bufferA transient pointer to the buffer that the checksum is to be computed for
Returns
The CRC-32 checksum of the input buffer.

◆ crc32_update()

std::uint32_t FEAT::Hash::crc32_update ( std::size_t  n,
const void *  buffer,
std::uint32_t  crc_in 
)
static

Updates a CRC-32 checksum of a buffer.

The polynomial for the CRC table is 0x04C11DB7.

Parameters
[in]nThe length of the input buffer in bytes.
[in]bufferA transient pointer to the buffer that the checksum is to be updated for
Returns
The updated raw CRC-32 checksum of the input buffer.
